Fix clang analyzer warning about FilterGenerator

Browse Source 
Refactor FilterGenerator to remove ctor call to overridden method next()
in order to address clang static analyzer diagnostic:

catch2-src/single_include/catch2/catch.hpp:4166:42: note: Call to virtual method 'FilterGenerator::next' during construction bypasses virtual dispatch
                auto has_initial_value = next();
                                         ^~~~~~
